Your company requires a Stack-based model for its resources in AWS. There is a need to have different stacks for the Development and Production environments. Which of the following can be used for this?

Answer options:

A.Use EC2 tags to define different stack layers for your resources.
B.Define the metadata for the different layers in DynamoDB.C.Use AWS OpsWorks to define the different layers for your application.
D.Use AWS Config to define the different layers for your application.

Correct Answer - C
The requirement can be fulfilled via the OpsWorks service. The AWS Documentation given below supports this requirement:
AWS OpsWorks Stacks lets you manage applications and servers on AWS and on-premises. With OpsWorks Stacks, you can model your application as a stack containing different layers, such as load balancing, database, and application server. You can deploy and configure Amazon EC2 instances in each layer or connect other resources such as Amazon RDS databases.

A stack is basically a collection of instances that are managed together for serving a common task.
Consider a sample stack whose purpose is to serve web applications. It will be comprised of the following instances.
A set of application server instances, each of which handles a portion of the incoming traffic.
A load balancer instance, which takes incoming traffic and distributes it across the application servers.
A database instance, which serves as a back-end data store for the application servers.
A common practice is to have multiple stacks that represent different environments. A typical set of stacks consists of:
A development stack to be used by developers to add features, fix bugs, and perform other development and maintenance tasks.
A staging stack to verify updates or fixes before exposing them publicly.
A production stack, which is the public-facing version that handles incoming requests from users.
